Dunstable solar panel questions answered
How much do solar panels cost in Dunstable?
A 3-4kWp system in Dunstable typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,760 kWh/year, paying for itself in 6-8 years.
What is the Smart Export Guarantee (SEG)?
The Smart Export Guarantee (SEG) requires licensed energy suppliers to offer a tariff to small-scale generators for electricity exported to the grid. Rates are typically 3-15p/kWh. You need a smart meter and an MCS-certified installation to be eligible.
Do I need planning permission for solar panels?
Most residential solar installations in the UK are permitted development and don't require planning permission, provided panels don't project more than 200mm from the roof surface. Listed buildings and conservation areas may have additional requirements.
What roof direction is best for solar panels in Dunstable?
South-facing roofs produce the most electricity (100% of potential). South-east and south-west roofs produce around 95%. East or west-facing roofs still produce 80-85%. North-facing roofs are generally not recommended for solar panels in the UK.
Can I sell excess solar electricity?
Yes. Under the UK's Smart Export Guarantee (SEG), you can sell surplus electricity at 3-15p/kWh. You need a smart meter and an MCS-certified installation. Your energy supplier pays you for every unit exported to the grid.
What is an EPC assessment and do I need one?
An Energy Performance Certificate (EPC) assessment rates your home's energy efficiency from A to G. While not required for solar installation, solar panels typically improve your EPC by 1-2 grades, which can increase your property value. An EPC costs around £60-£120.
How does shading affect solar panels in Dunstable?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
